An airplane pilot looks down at a fire with an angle of depression of 20 degrees. the plane is flying at an altitude of 3500 feet. what is the horizontal distance?

a) 1274 ft
b) 9616 ft
c) 10233 ft
d) 1197 ft

answer:

your answer is: c. 196 7/8 in^3.

80

step-by-step explanation:

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3
